LAS VEGAS, Nevada -

The online dating service says a Las Vegas woman has no legal basis for her lawsuit of $10 million. Mary Kay Beckman filed suit in U.S. District Court on Friday accusing of failing to disclose dangers of online dating. Beckman claims she was matched with Wade Ridley and that he hid in her garage and brutally attacked her.

She said she'd known him only eight days before breaking up with him in September 2010. Four months later he stabbed her 10 times. He later was charged with murdering a woman in Phoenix. He died in prison last year. said in a statement Monday that Beckman's experience was horrible but the lawsuit is "absurd." It said Beckman was a victim of a "sick, twisted" man with no known criminal record.
